If you have a watch with hands and the sun is out you don't need a compass.
If you line up the sun with the little hand that points to the hour, then due south is halfway between the sun and 12, trust me it works, it is an old orienteering trick, so you can find your way around without a compass.
It does'nt work at night though

If the stars are out, look for the big dipper, and the 2 end stars point up to the Pole Star which is due North.
I need to get out more, I'm so lonely.
